Toxic effects of polychlorinated biphenyls (Aroclor 1254) on human sperm motility
Polychlorinated biphenyls (PCBs) are common environmental contaminants that represent a considerable risk to reproductive toxicity in exposed human populations. Although some experimental studies have suggested an association between the levels of PCBs and semen quality, the direct effects of PCBs on human sperm parameters remain largely unexplored. To this aim, a short-term in vitro incubation...
متن کاملEffect of polychlorinated biphenyl, Aroclor 1254 on rat epididymis.
BACKGROUND & OBJECTIVES Polychlorinated biphenyls (PCB), the synthetic chlorinated organic compounds, are known to decrease thyroid function, sperm count and fertility, and increase the risk of testicular cancer may cause serious effect on male reproduction. The objective of the present study was to study the effect of PCB, Aroclor 1254 on rat epididymal structure and function. METHODS Adult ...
متن کاملPolychlorinated Biphenyls (Aroclor 1242): Effects of Uptake on E. coli Growth
Polychlorinated biphenyls (PCBs), similar to DDT in structure and physiological effects (7), are of concern to the scientific community because of their ubiquity (8), persistence (11) and possible toxicity. The alleged lack of biodegradability of this environmental pollutant has caused alarm and curtailment of this useful chemical. Work as early as 1963 by Cope (3) indicated that DDT, another c...
متن کاملEffects of aqueous exposure to polychlorinated biphenyls (Aroclor 1254) on physiology and behavior of smolt development of Atlantic salmon.
Polychlorinated biphenyls (PCBs) are a widespread aquatic contaminant and are present in both wild and hatchery raised Atlantic salmon, Salmo salar. The possible sub-lethal alterations in smolt physiology and behavior due to PCB exposure of salmon have not been widely examined. In this study, we examined the effects of the PCB mixture Aroclor 1254 on survival and smolt development of Atlantic s...
متن کاملGender-dependent behavioral and sensory effects of a commercial mixture of polychlorinated biphenyls (Aroclor 1254) in rats.
Developmental exposure to polychlorinated biphenyls (PCBs) has been associated with behavioral and cognitive deficits in humans and animal models. Perinatal exposure to PCBs has also been associated with sensory deficits in animal models. These effects were hypothesized to be mediated in part by ortho-substituted PCBs, which do not or weakly bind to the aryl hydrocarbon (Ah) receptor. The prese...
